Environmental Science Practice Test

Build high school Environmental Science skills with original questions on ecosystems, biodiversity, resources, pollution, climate change, data, policy, and sustainable solutions.

Environmental Science practice sets

This high school Environmental Science practice hub includes five short sets of 10 original questions. The sets cover ecosystems and biodiversity, natural resources and sustainability, pollution and environmental health, climate and global systems, and environmental data, policy, and solutions.

Course scope and standards

The course connects living systems with Earth materials, natural resources, hazards, pollution, climate change, human health, biodiversity, conservation, and environmental decision-making. Expectations vary by state, school, and course sequence. The topic structure is a supplemental study map to the high-school Earth and Human Activity expectations in the Next Generation Science Standards HS-ESS3, including resource management, pollution, climate evidence, systems modeling, and solution tradeoffs.

Skills covered

  • Explain ecosystem structure, energy flow, biodiversity, population limits, succession, and species interactions
  • Evaluate renewable and nonrenewable resources, water and soil systems, agriculture, fisheries, and sustainability
  • Connect pollution sources with exposure, health effects, food webs, waste, and ecosystem response
  • Interpret climate evidence, carbon-cycle changes, feedbacks, models, mitigation, and adaptation
  • Analyze environmental data and compare solutions using evidence, constraints, tradeoffs, equity, and long-term system effects

How to use these practice tests

Start with the set that matches your current unit. For missed questions, identify the system boundary, the cause and effect, and the evidence supporting the answer. When a solution is proposed, compare its effectiveness, cost, safety, environmental impact, uncertainty, and effects on different communities.

These are original supplemental practice questions. They are not an official state assessment, school examination, NGSS test, AP Environmental Science exam, or test-provider assessment. Confirm your course standards, assessment blueprint, laboratory expectations, and accommodations with your teacher or school.

1. QuestionMultiple choice

Why should an environmental investigation define its system boundary?

Please select an answer first.

Correct answer: A

The correct answer is The boundary identifies what inputs, outputs, variables, and interactions are included in the analysis.

  1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
  2. Connect the evidence: A clear boundary makes assumptions and relationships explicit and helps prevent unsupported conclusions.
  3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

A clear boundary makes assumptions and relationships explicit and helps prevent unsupported conclusions.

2. QuestionMultiple choice

What is environmental justice concerned with?

Please select an answer first.

Correct answer: B

The correct answer is Fair treatment and meaningful involvement of people in environmental decisions and burdens.

  1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
  2. Connect the evidence: Environmental decisions can distribute risks, benefits, access, and participation unevenly across communities.
  3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Environmental decisions can distribute risks, benefits, access, and participation unevenly across communities.

3. QuestionMultiple choice

Which factor is a valid constraint when comparing environmental solutions?

Please select an answer first.

Correct answer: C

The correct answer is Cost, safety, reliability, effectiveness, ecological impact, and community effects.

  1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
  2. Connect the evidence: Engineering and policy choices should state criteria and constraints before alternatives are compared.
  3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Engineering and policy choices should state criteria and constraints before alternatives are compared.

4. QuestionMultiple choice

What does a dose-response relationship describe?

Please select an answer first.

Correct answer: D

The correct answer is How the effect on an organism or population changes as exposure amount changes.

  1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
  2. Connect the evidence: Dose-response evidence helps evaluate how exposure level relates to a biological or health outcome.
  3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Dose-response evidence helps evaluate how exposure level relates to a biological or health outcome.

5. QuestionMultiple choice

Why is a control or reference site useful in an environmental study?

Please select an answer first.

Correct answer: A

The correct answer is It provides a comparison that helps separate the effect of the tested factor from background variation.

  1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
  2. Connect the evidence: A comparison site can help identify changes associated with an intervention or exposure.
  3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

A comparison site can help identify changes associated with an intervention or exposure.

6. QuestionMultiple choice

What is the best first step when reading an environmental graph?

Please select an answer first.

Correct answer: B

The correct answer is Identify the variables, units, scale, time period, source, and uncertainty.

  1. Identify the environmental system: Determine whether the prompt concerns ecosystems, resources, pollution, climate, human impacts, policy, or environmental data.
  2. Connect the evidence: Interpreting the representation and its limits is necessary before making a claim.
  3. Check the tradeoff or relationship: Compare the answer with the stated data, system boundary, cause, effect, or solution constraint before choosing.

Interpreting the representation and its limits is necessary before making a claim.

7. QuestionMultiple choice

Why can conservation areas be connected by wildlife corridors?
